Boats, of which the following, is a specification.

This invention relates tocertain new and useful lmprovements 1n submarine boats and it has for its objects among others to pro-" vide a novel construction of hull whereby the boat may be better balanced and more easily controlled, whereby it may be madev to automatically dive or rise by the shifting of the center of gravity, and, consequently, make the resistance of the water upon its inclined deck greater or less at any regular velocity, and as the velocity becomes greater the resistance increases proportionate to the shifting of the center of gravity. M

1 construct the boat of such a shape as to. accomplish this object, without the employment of planes'or rudders or any other form of external attachment. In my boatthere are no lateral projections, everything being confined within the cross sectional area of the boat. The'boat is-constructed with a fiat upper surface extending from its widest point to the bow and downwardly at an angle to the longitudinalaxis of the boat. This flat surface extends from the conning tower to the prow of the boat. This offers great resistance to the upward or rising movement of the prow. The stern is formed upon lines which are novel and which tend to offer less resistance, being curved downwardly and rearwardly, from the rear of the conning tower to the extreme stern of the boat.

By altering the resistance of the water upon the .boat, I can cause it to rise or sink to any desired depth.

The boat may be propelled by any suitable means, such, for instance, as by the generation of steam by means of'burning crude oil, gasolene, coal oil or any of its refined products, or any other burning fuel which can be converted into units of exertion. The present invention, however, pertains to the shape of the body regardless of the manner in which it is propelled or the means for or manner of shifting its center of gravity.

Other objects and advantages of the invention will hereinafter appear and the Specification of Letters Patent.

novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which Figure 1 is a side elevation of a submarine constructed in accordance with mypresent invention.

Fig. 2 is a view looking at the bow.

. Fig. 3is a View looking at the stern.

Fig. t illustrates the crosssectional formof the boat at or near midship, the conning tower being removed. a i

Like numerals of reference indicate like parts throughout the several views. I

Referring to the drawings, j 1 designates the boat proper, the interior of which does not pertain to the present invention and hence the exterior appearance only has been illustrated. As will be seen upon referencetothe difierent figures of the drawing, the boat has a substantially smooth exterior, being constructed without vanes or blades or other extraneous means, and, in fact, devoid of all means or pro jections extending beyond the sides or ends of the boat and, hence, avoiding liability of such projections, as vanes or the like, retarding theprogress of the boat orv endangering the same by coming in contact entinvention and may be of any wellknown or approved form. of construction operating in any well-known way. I

Forward of this portion 2 there is a comparatively narrow projection 42 having a flat upper face 5 and which may constitute a deck which may be readily reached from the conning tower, this projection l having convergent sides 6, 6, as seen best in Fig. 2-, and the forward end of which is preferably concaved or upon inwardly receding curved lines, as seen at 7 in Fig. 1. I Forward of this member formed with a substantially flat upper portion, as seen at 8, extending the fullwidth 4, the I hull is v of the hull to the prow 9, as seen in Fig. 2, the forward end thereof being inclined,,as seen at it), and terminating at a point 11. The bottom of the boat is rounded, as seen in Figs. 2. 3 and i. the same mending ackward to the point 12, Fig. 4. representing a vertical cross section of the hull at point slightly forward of the point 12, and from which point the bottom extends rearwardly and upwardly upon curved lines, as seen at 13, the upper face of the portion to the rear of the portion 2 being upon curved lines, as seen at '14-, and ext-ending for the full width of the hull at the rear of the conning tower, to a point 15, as seen in Figs. 1 and 3.

As shown in the present instance, twin propellers 16 are provided for the propulsion of the boat and these may be driven in any suitable or well-known way.

The line o-a in Fig. l designates the water line when the boat is not submerged. The hull is so constructed that the proportion of the weight is such that when in the position seen in nig. 1, the broad fiat upper surface 8 of the prow of the-boat offers sufficient resistance to the tendency of the boat to rise at the bow, to keep the same down so that the boat will ride with the bottom at substantially the angle to the horizontal, as seen in said'Fig. 1. increased speed and consequentgreater tendency of the boat to rise at the bow are compensated for by the resistance offered by the broad and flattened forward portion of the upper surface of the boat. Variations in speed, and shifting of the center of gravity regulates the diving or rising of the boat by the consequent resistance of the water upon the inclined deck; as the velocity becomes greater the resistance increases proportionately. This shifting of the center of gravity may be accomplished' in any suitable manner, by the concentration of any weight at any one particular position on the boat, and the velocity of the boat is controlled by whatever means of propulsion the boat may be equipped with. The shape of the hull is the controlling element in the rise and fall of the boat.

The construction is such as to not only slightly restrict the tendencyofthe bow to sink or to vibrate up or down, but it aids in insuring a more steady diving and doing away with tendency to wabble while submerged.

By reason of the particular construction of the boat, all extraneous projections, such as vanes or the like, which would tend to retard its progress, are avoided, as well as liability of injury to the boat by thev presence of such projections. The absence of these lateral projections enables me to provide a boat with a smooth unobstructed outer surface, giving every advantage obtainable for maximum speed with minimum power.

From the foregoing, it will be seen that I have devised a boat whose shape is such that it uses the resistance of the water to submerge or ris ant while the structural embodiment of the invention as herein dis closed is what I at the present time consider preferable, it is evident that the same is subj ect to changes, variations and modifications in detail, proportion of parts, etc, without departing from the spirit of the invention or sacrificing any of its advantages and which details may be changed from time to time according to requirements. I, therefore, do not intend to restrict myself to the precise construction, arrangement and proportion of parts hereinbefore disclosed, but reserve the right to make such changes, variations and modifications as come prop erly within the scope of the protection prayed.

It is evident that the shifting of gravity may be done by the concentration of any weight at any particular part of the boat and which weight can be a suitable carriage in which may be placed excess baggage which when used can be replaced by water.
